#1 Crash on startup because of GLXBadFBConfig

Hiii!

On startup, I get the following error:

X Error:
GLXBadFBConfig

    cannot create gl context

I have working OpenGL, so this is obviously not it. glxinfo returns the following (among other things):

OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) HD Graphics 2500 (IVB GT1)
OpenGL core profile version string: 4.2 (Core Profile) Mesa 22.3.2
OpenGL core profile shading language version string: 4.20
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

The error also persists if I set the environment variable LIBGL_ALWAYS_SOFTWARE=1 (which forces OpenGL software rendering).

Some relevant pieces of strace:
